/* INTRODUCTION
The or1ksim have various parameters, which can be set in configuration
files. Multiple configurations may be used and switched between at
or1ksim startup.
By default, or1ksim loads condfiguration file from './sim.cfg' and if not
found it checks '~/.or1k/sim.cfg'. If even this file is not found or
all parameters are not defined, default configuration is used.
Users should not rely on default configuration, but rather redefine all
critical settings, since default configuration may differ in newer
versions of the or1ksim.
If multiple configurations are used, user can switch between them by
supplying -f <filename.cfg> option when starting simulator.
This file may contain (standard C) only comments - no // support.
Like normal configuration file, this file is divided in sections,
where each section is described in detail also.
Some section also have subsections. One example of such subsection is
block:
device <index>
instance specific parameters...
enddevice
which creates a device instance.

/* MEMORY SECTION
This section specifies how is initial memory generated and which blocks
it consist of.
type = random/unknown/pattern
specifies the initial memory values. 'random' parameter generate
random memory using seed 'random_seed' parameter. 'pattern' parameter
fills memory with 'pattern' parameter and 'unknown' does not specify
how memory should be generated - the fastest option.
